• Address P2_0Ch: TG CIS_CLK/SH On Guardband Register

Bit

Mode

Description

Default

7-0

R/W

CIS_CLK on guardband. Number of pixel periods from end of the SH

pulse to start of CIS_CLK.

• Address P2_0Dh: TG CIS_CLK/SH Off Guardband Register

Bit

Mode

Description

Default

7-0

R/W

CIS_CLK off guardband. Number of pixel periods before start of the

SH pulse that CIS_CLK stops.

R/W

TG wheel Step Most Significant 3 Bits

Wheel Step is from 1.0~8.0 mm/step and wheel step should multiply

128 to set the whole register

Ex: @100DPI,

1 mm/step = 4 lines/step

2 mm/step = 8 lines/step

R/W

TG wheel Step Least Significant Byte

Wheel Step is from 1.0~8.0 mm/step and wheel step should multiply

128 to set the whole register
